Built for medical nebulizer systems, respiratory therapy devices, and inhalation drug delivery equipment, Medical LSR Overmolded Nebulizer Cup with PC Housing is a medical and healthcare silicone component centered on material system: Liquid Silicone Rubber + Polycarbonate; process: Two-Shot Injection Molding (LSR Over PC); base material: Medical Grade PC. This configuration is intended for buyers who need a production-ready part rather than a generic off-the-shelf silicone item.
Para programas OEM e personalizados, as questões práticas são: como a peça se encaixa, a que ela deve resistir e quais dimensões ou interfaces são essenciais. As seções a seguir separam os requisitos de desempenho, as informações sobre materiais e processos e os detalhes da aplicação, para que o produto possa ser avaliado com mais eficiência.
Prioridades de design funcional
- The overmolded silicone material is specially formulated for medical applications. It offers excellent biocompatibility and is suitable for inhalation-related environments.
- ISO 10993 biocompatibility compliant
- USP Class VI certified material
- Odorless, non-toxic, and stable under long-term use
- Developed for direct or indirect patient contact
- The LSR is permanently bonded to the PC substrate through precision injection molding, forming a seamless sealing interface.
- Eliminates traditional O-rings and manual assembly

Design Notes for Production
- The product is produced through a precision two-step injection molding process:
- PC Injection Molding Medical-grade polycarbonate is molded into the structural base, forming the rigid housing and internal flow channels.
- LSR Overmolding Liquid silicone rubber is injected onto the PC substrate, forming soft sealing structures and functional interfaces.
- Permanent Bonding Formation Under controlled temperature and pressure, LSR chemically or mechanically bonds with PC, forming a durable integrated structure.
- Silicone rubber has natural chemical inertness, making adhesion to PC challenging. This is solved through:
- Self-bonding medical-grade LSR formulations
FAQ for Engineering Buyers
What is the benefit of LSR overmolding compared to traditional assembly?
LSR overmolding eliminates separate sealing components such as O-rings, reducing leakage risk and improving long-term stability.
Is the product suitable for repeated sterilization?
Yes, it is designed for repeated autoclave sterilization between 121°C and 134°C without performance degradation.
Does the silicone become hard or degrade over time?
Medical-grade LSR maintains elasticity and mechanical stability under long-term use.
